From the Public Sector to a Frontline NGO: An Idealist in Yunnan

How did an organisation focused on insect ecology start caring about farmers’ livelihoods? And how did an organisation focused on farmers’ livelihoods end up composing a song called Song of the Fly?
A man from Shanxi — how did he become the village’s “male women’s committee director”? A star graduate in genetic engineering — why is he out in the fields urging farmers to grow crops without pesticides or chemical fertilisers?
How did these seemingly unrelated people and events manage to weave together so remarkably?
For this episode, we’ve invited Zuo Zhi, executive director of the Yunnan Sili Ecological Substitution Technology Center. A Shanxi native born after 1985 who walked into Yunnan’s villages, he left the public sector after university to join an NGO called “Sili” to do something that’s not the easiest thing to explain: teaching farmers to use fewer pesticides, to grow landrace rice, and trying to build a bridge between government, farmers, and technology.
You’ll hear some details that run counter to common sense: the fly turns out to be the top “matchmaker” in mango orchards, and the first step in promoting ecological agriculture was draining the glass of liquor already in the farmer’s hand. From Dali’s Rice Planting Festival to the yield-measurement fields of the Hani Rice Terraces, Zuo Zhi takes us through the interplay between agri-input shops, agricultural extension stations, and civil organisations, unpacking what “climate-friendly rice” means when it comes to maintaining yields while cutting emissions.
In this episode, we’ve walked alongside Zuo Zhi to document how an idealist gets down into the fields by “speaking in plain terms”. This is not just a popular-science piece on “climate-friendly rice”; it’s a genuine record of how, within the constraints of reality, small changes can build trust and tend to rural communities.

30:21 Government, agri-input shops, NGOs: who is shaping how farmers grow their crops?
38:50 Climate-friendly rice: not just growing crops, but “working in coordination” with the weather

Yunnan Sili Ecological Substitution Technology Center (abbreviated as “Sili Centre”), founded in 2002, works around sustainable agricultural development, carrying out community pesticide risk management, research and extension of ecologically and climate-friendly applied technologies, agricultural biodiversity conservation, and public science outreach. It advances synergistic pollution reduction and carbon mitigation in agriculture, promoting sustainable social and economic utilisation.
